I have an iMac running Mac OS X 10.5.6, running on my local network with a fixed IP 192.168.0.98.
On this machine I have two users: "john" who has the root privileges and "mary" who is a regular user.
When John executes:
ssh mary@localhost
he gets asked three times...
I was using until recently a PowerPC running Mac OS X 10.4.11. Since I maintain my directories synchronized all the time between Linux running on another machine and this PowerPC, I created a link:
/home -> /Users
so that all my scrpits and links (like /home/....) would work properly...
